Note 9 - Fair Value Measurements
We follow fair value measurement accounting guidance for all assets and liabilities measured at fair value. This guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Market or observable inputs are the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The fair value hierarchy for grouping these assets and liabilities is based on the significance level of the following inputs:
•Level 1 – quoted prices in active markets for identical assets or liabilities
•Level 2 – quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose inputs are observable or whose significant value drivers are observable
•Level 3 – significant inputs to the valuation model are unobservable
The following table is a listing of our assets and liabilities that are measured at fair value on a recurring basis in the accompanying balance sheets and where they are classified within the fair value hierarchy:

Both financial and non-financial assets and liabilities are categorized within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The following is a description of the valuation methodologies we use as well as the general classification of such instruments pursuant to the above fair value hierarchy.
Derivatives
We use Level 2 inputs to measure the fair value of oil, gas, and NGL commodity derivative instruments. Fair values are based upon interpolated data. We derive internal valuation estimates taking into consideration forward commodity price curves, counterparties’ credit ratings, our credit rating, and the time value of money. These valuations are then compared to the respective counterparties’ mark-to-market statements. The considered factors result in an estimated exit price that management believes provides a reasonable and consistent methodology for valuing derivative instruments. The commodity derivative instruments we utilize are not considered by management to be complex, structured, or illiquid. The oil, gas, and NGL commodity derivative markets are highly active. Refer to Note 8 - Derivative Financial Instruments for more information regarding our derivative instruments.
Acquisition of Proved and Unproved Properties
Assets acquired and liabilities assumed in transactions that meet the definition of a business combination under ASC 805 are recognized at their estimated fair values as of the acquisition date and are valued using an income valuation technique based on Level 3 inputs. Refer to Note 2 - Mergers, Acquisitions, and Divestitures for discussion of the valuation technique used for the Merger.
Long-Term Debt
The following table reflects the fair value of our Senior Notes obligations measured using Level 1 inputs based on quoted secondary market trading prices. The Senior Notes were not presented at fair value in the accompanying balance sheets as of June 30, 2026, or December 31, 2025, as the Senior Notes were recorded at carrying value, net of any unamortized premium or unamortized deferred financing costs. Refer to Note 6 - Long-Term Debt for additional information.
